I am experimenting with different shafts in a TS3 five iron head.
Currently I have a Fujikura Vista Pro 60i R flex shaft in the 5 iron. I hit it OK.
It was suggested to try the Maltby MPF Pro Series iron shafts
I am 3B2M using the MPF ratings.
The MPF Pro SERIES IRONS, R flex is a 3B3M.
Is there going to be a noticable difference going to this shaft?
